A classic style pullover hoodie appears in 2019.
This is a fall season item, and features arms-crossed classic Sonic on the front. It spells out his name in mis-matched (looks almost like those magazine clipping type) letters vertically down one side. The shoulders area is blue, as is the interior of the hood, and the rest is black. It has the full color classic logo on the upper chest area. It has a short, black zipper that only goes maybe about a third of the way down, so it really is a pullover. This is a 'teens' size item, which means it could fit most people. It's also pretty reasonably priced at 19.00 as well. It should be an Amazon item.
You can see the embroidered back tag there in the collar, it just seems to have the classic logo on it so the brand is unknown.
